Dehydration you need to take care of obviously. (Maybe has to do with the kidney issue?)

As for all the infection stuff: If your body can get used to the steady medication, without big dosage adjustings to the main medication that affects the immune system, then this getting sick so often also will become less. Immune system keeps aligning to this after a longer amount of time.When it's the same for, let's say. a year or so, then this effect will be there.Cortisol metabolism, immune system and ongoings in the spinal marrow are some of those things in the body that take very long to experience change when something's wrong or something's new in there.
